To all whom, it may cancers:

Be it known that I, FRED S. CARR, a citizen of the United States, and a resident of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Stndand-Socket Fasteners, of which the following is a specification.

This invention relates to devices of the snap fastener type, comprising a stud member and a socket member which in use are connected to two holders or carrying parts usually of flexible material, such as the ma terial of which gloves are made. It is to be understood at the outset, however, that I do not limit myself to any particular article or articles by which-the two members of the fastener are carried.

One of the objects of the invention is to provide a simple, inexpensive and extremely compact device of the type mentioned, the

compactness consisting in the size of the stud member or of the two members assem bled as to their thickness and not the lateral dimensions.

A further object is to provide a device of this type with a stud member having an open recessed face so that although the means for attaching said member to the carrying part is within the area of the member, yet such means for attaching will not interfere with the coupling of the two members together.

A further object of the invention is to provide a structure of the .two members of the device which will give the maximum amount of gripping surfaces for a given size of fastener.

Further objects are to provide for the greatest amount of durability and resistance to separation or" the two parts.

To these ends the invention consists in the improvements which I shall now describe and claim.

Of the accompanying drawings :Figures 1 and 2 are inner face views of the stud and socket members respectively. Fig. 3 represents the two members in transverse section', separated but about to be assembled,

said figure also illustrating carrying parts or holders for the two members. Figs. 1 and 5 are views similar to a portion of Fig. 3 illustrating different forms of said members. Fig. 6 is a view similar to Fi 3 but showing the two members assembl .less than the diameter 7 ring 13, as indicated in Fig. 3, so thatsaid 'tere with the assembling sauna-sooner recreates;

The same reference characters indicate the same parts in all the figures.

The socket, member comprises a base 12 having an externally curved rim 13, said base having suitable'means whereby it may be secured to a holder or carrying part which may be fabric but which is illustrated in Fig. 3 as a portion of a wood support. In Figs. 1 and 3'thc means for attaching is illustrated as comprising a hole 14 through which a screw may be passed into a rigid support orholder. Mounted in the groove of the ring 13 is a spring 15 consisti single piece of spring wire substantial f circular in form, the ends of the wire meeting as at 16 when in the normal position shown in Fig. 1. The diameter of the circle of the, outer surface of the spring 15 is slightly of the groove in the spring may be slightly opened or expanded as hereinafter described. Between the base 12 and the ring 13 the socket member is shouldered as at 17 to provide a slightly deeper rccess in the socket member tosnugly receive the stud member, said stud member comprising a base 18 having-an externallyv curved rim 19.

The base 18 is formed so that it may be attached to a holder or carrying part such as a piece of fabric, as by means'of threads passed through holes 20' in the base 18. The stud member is formed with a central recess or concavity 21 which will permit of the attaching means which secures said member to the holder or carrying part, to be located in. said recess in the position where such attaching means cannot inter as the stud and socket members. The structure of said member illustrated in Figs. 2 and 3 is one which permits of the device being made of thin sheet metal having a spun or rolled edge to form the engaging rim 19. In Fig. a I show a stud member which is made of thicker sheet metal andis simply dished, the base 18 having thread holes 20 and the rim l9 being rounded, the dish-shaped form. indicated providing for a recess or con cavity 21 to receive the attaching means.

In Fig. 5 1 illustrate a structure similar to that in Figs. 2 and'S, the base 18 having a curved rim 19 presenting a recess or concavity 21. 1 In said Fig. 5, however, the means for attaching the stud member to the holder or carrying part consists of astud or tubular portion adapted to be riveted to the holder ,or carrying part.

i do not limit myself to any particular means for attaching the members of the 't-istener to their holders or carrying parts, so long as such attaching means are located inside of the engaging margins of the two members, each member being open faced and presenting a recess or concavity to receive portions of the means which attach the members to their carrying parts. This structure enables me to provide a stud and socket fastener which is very thin or in other words 1s exceedingly compact although its lateral area may be as large as desired according to the articles which are to be held together by the "fastener, and according to the strain to which such articles may be subjected. The outermost diameter of the stud. member engages the socket member and presents no base or attaching member which exposed outside of the margin of the gripping rim. The structure is such that for a given size of fastener laterally, the greatest possible amount of gripping surface is provided so as to provide for extreme durability and iesistance to separation.

its best shown in Fig. 6, the structure is such that when the two members are assembled, the stud member passes entirely within the socket member and is entirely. concealed thereby, the margin of rim 13 bear ing against the face of the holder for the stud member.

As clearly shownby comparing Figs. 3 and 6, the two members are shallow and relatively wide, and the spring is of such size as to provide an exceedingly durable fastener, and yet one which can be readily assembled and disassembled. Moreover, the structure is such that neither member requires that any portion thereof shall project through an opening in the carrying part, or

produce a bump in that carrying part.

lhe annular shoulder 17 possesses two functions; it supports the spring against 1nward pressure when the parts are being assen'ibled, and after the parts are assembled it confines the stud member against lateral movement. The 'spring returns to its normal position as soon as the members are assembled, being no longer held expanded by the stud member. This provision of the annular shoulder 17 below the internal groove insures the proper retention of the spring between said shoulder and the ex treme edge of the rim, and at the same time results in the formation of a shallow space which receives and laterally confines the flaring rim of the stud member.

The stud member shown in 5, instead of being attached to its holder by utilizing the tubular portion 20 as a rivet, might be attached by passing a rivet or screw through said tubular portion.

, I claim A fastener of the character described, comprising a socket member having a substantially fiat attaching base and a rim formed with an annular shoulder and an internal groove above said shoulder, the treme edge of the rim consti uting the margin of an opening the diameter of which is substantially the same as the diameter of the space within said shoulder, a ring-shaped spring confined in said groove between the shoulder and the extreme edge of the rim, the internal diameter of the spring being less than that of the shoulder and the openin and a stud member having a substantially flat attaching base and a flaring rim, the external diameter of the latter being greater than the normal internal diameter of the spring and slightly less than the internal diameter of the socket member below the shoulder of the latter to be held thereby against lateral displacement when the members are assembled, the space within the socket member being shallow and relatively wide, and adapted to receive and entirely conceal the stud member.

In testimony whereof I have aiiixed my signature, in presence of two witnesses.
